Hi Mara,
Several suggestions:
Put the password in a list, then loop each letter to check if it is a vowel
like this
password=[]
vowels=['a','e','i','o','u'] #in your message, u is missing, BTW
password=input("Enter a password:")
for p in password:
if p in vowels:
return True #I would use print("the message that you want to
display") though.
else:
return False
And how about error handling? You put
if len(y) ==0:
return True #I would use print("woops! You did not enter
anything.") and add break
Does this password case sensitive? If so, add AEIOU in vowels list.
Good luck!
Noriko

Hi everyone, trying to write a program that has the user enter a password,
checks if it contains any vowels, and if it does prints ' It is false that
password(whatever the user enters) has no vowels,' and if it has no vowels
prints it is True that password has no vowels...
Here is what I have so far...
def password(y):
vowels=["a","e","i","o"]
if y[0] in vowels:
return False
if len(y) ==0:
return True
elif(y[len(y)-1] != vowels):
return False
else:
return password(y[1:len(y)-1])
x=input("Enter a password:")
print("It is", password(x),"that",x,"has no vowles")
As of now it just asks for the password, and then prints 'It is False that
password(whatever was entered) has no vowles' for any word I enter. I think
maybe some of my if statement conditions may be being returned to the function,
but then not printing the appropriate one? Can anyone help? Thanks!
It appears that the issue is from this:
elif(y[len(y)-1] != vowels):
This condition will be true because you are comparing a string with a list.
Thus causing passwrod() returning False.
